I found an offer for Nikon S + lens for $1800.
There may be oil ....
		
		
	 
Awesome deal, grab it.
Is it the internal version or the external version?
I have been tracking prices and the internal version seems to be cheaper than the external version. Here is what the last two brought in Westlicht auction

I see the external mount has gone up and the internal gone down in price.
Kevin Cameras has a few but the prices are over $5k
